Background info…

The NORAD Tracks Santa program began as an annual event on December 24, 1955. According to legend, a Sears department store placed an advertisement in a Colorado Springs, Colorado, newspaper which told children that they could place a call to Santa Claus. It included the number ME 2-6681. A call allegedly came through to Colorado Springs’ Continental Air Defense Command (CONAD) Center as one digit was misprinted.

In some versions of the story, the calls were coming in to the “red telephone” hotline that connected CONAD directly to command authorities at the Strategic Air Command. Colonel Harry Shoup, who was a Crew Commander on duty, answered the first call and supposedly told his staff to give all children who called in later a “current location” for Santa Claus.
